Asbestos Testing in Toronto

Full price list: asbestos testing cost in Canada.

We test Toronto homes, rentals, condos and commercial buildings for asbestos before renovation, demolition or purchase. Our own inspector samples each suspect material, an accredited lab analyzes it under a microscope, and you get a written yes or no for every material, with its asbestos type and percentage. The first material is CAD 430 plus tax and each extra one is CAD 250.

Most people call us at the same moment: a contractor has asked what's in the ceiling, or the drywall is coming down next week. That's the right time to ask. Everything about our asbestos testing service is built around one question, which is whether the material you're about to cut is safe to cut.

Toronto's housing is old by Canadian standards. In the 2021 census, 58.1% of the city's 1.16 million homes were built before 1981 and 67.5% before 1991. Put another way, if you pick any two homes on a Toronto block, odds are at least one of them was finished while asbestos products were still on store shelves.

The dates matter because different materials stopped at different times. Ontario's Ministry of Labour guide says asbestos was widely used in sprayed-on material and in pipe and boiler insulation until 1973, and that many other asbestos products continued until the mid 1980s. Health Canada uses 1990 as its line, and asbestos products have been banned in Canada since 2018. The bans don't reach back into walls that were closed up decades ago.

The Canadian Centre for Occupational Health and Safety says it plainly: you can't tell if a product contains asbestos by looking at it, and the only way to know is a lab test. Two popcorn ceilings from the same year, on the same street, can come back different, which is why each one gets its own sample.

That cuts both ways, honestly. An old material isn't automatically dangerous, and a newer-looking one isn't automatically clean. Health Canada says asbestos poses no significant health risk when it's left undisturbed, sealed behind walls or floorboards, or tightly bound and in good condition. The risk starts when someone drills, sands, scrapes or breaks it.

We don't test a whole house by default. We test what the work will touch. A kitchen reno usually means floor tile, the glue under it and the drywall joint compound. Finishing a basement can add a ceiling texture, plaster and the old wrap on furnace ducts. Here's where each material tends to show up in Toronto:

Ontario's rules are in Ontario Regulation 278/05, and they treat four kinds of people differently. We're inspectors, not lawyers, so read this as a plain-language map and get advice if your case is close.

1. 1

   Before the visit

   You tell us what's coming out

   Call or send the form with the rooms and materials the work will touch. You get a flat-rate quote by material.

2. 2

   Visit day

   We sample with as little dust as possible

   The inspector cuts a small piece with clean tools, wets it to limit dust and seals it in a labelled container. Each sample is photographed and logged by location.

3. 3

   Within 1 business day of the visit

   You get the written inspection report

   What we sampled, where, and why, with photos of each spot.

4. 4

   3 to 4 business days

   The accredited lab returns its results

   Asbestos type and percentage for each sample. Rush analysis is available for an added fee.

The sample count is where owners get confused. A homeowner who just wants to know before opening a ceiling usually needs one sample per material. An owner covered by the regulation has to meet its minimums in Table 1: three samples for most materials, and three, five or seven for sprayed or trowelled surfacing depending on its area (the Toronto air quality testing page has that full "3-5-7" table). The minimum is set by the material and its area, not by how big your house is. We'll tell you which case you're in when we quote.

You can read more about what happens during an inspection before you book.

Yes, you can buy a kit, cut your own piece and mail it to a lab. For a homeowner in their own house that's legal, and the lab result itself can be perfectly accurate. We won't pretend otherwise.

The trouble is everything around the result. CCOHS advises homeowners not to remove or disturb suspect material themselves, and cutting a sample is disturbing it. A kit won't tell you which areas count as one material, how many samples a contractor or condo board will expect, or what to do when the drywall in the basement isn't the same drywall as upstairs. And a single result in an envelope isn't the location-by-location written report your contractor needs to plan the work.

Lots of pages online mix these up. They're two different tests for two different moments.

An air test before a renovation can't tell you what's inside a ceiling that hasn't been touched yet. That's why we almost always start with the material.

A home inspector will often write "possible asbestos" next to a ceiling or a furnace wrap. That's a flag, not an answer. If you're planning a renovation after closing, sample the materials that renovation will touch: the kitchen floor, the basement ceiling you want to drywall over, the duct wrap if the furnace is going.

Timing is the catch. The written report comes within 1 business day of the visit and lab results in 3 to 4 business days, so it fits inside a conditional period only if the seller gives access early. Our air quality testing for home buyers guide covers what else is worth checking before you firm up.

Each sample comes back with the asbestos type, if any, and its percentage. Under Ontario's regulation, a material with 0.5% or more asbestos by dry weight is asbestos-containing, and one positive result makes the whole area of that material asbestos-containing. The lab can stop analyzing the rest of that set once it finds one.

A positive result is a planning fact, not an emergency. If you're not renovating, the material can often stay exactly where it is. If you are, a qualified abatement contractor removes it before the rest of the work, using the procedures the regulation sets for that type of job. We don't do asbestos abatement or removal. Our report goes to whichever contractor you hire, and we can come back for the clearance air test when they're done.

One practical Toronto detail: the City's drop-off depots don't accept asbestos. Disposal is a job for a private company, which is one more reason it belongs with your abatement contractor and not in your car trunk.

Toronto prices are the same as everywhere else we work, with no travel fee in the GTA. All prices are in Canadian dollars, plus tax.

Slow down here, because the material count is what moves the bill. A few typical Toronto jobs, sampled once per material:

• A 1970s Scarborough kitchen with floor tile and drywall compound coming out: two materials, $680.
• Finishing the basement of a 1960s Etobicoke bungalow, touching the stipple ceiling, floor tile, plaster and furnace duct wrap: four materials, $1,180.
• Gutting a pre-war Leslieville semi, with plaster, floor tile, pipe wrap, ceiling texture and drywall compound: five materials, $1,430.

You'll see lower Toronto prices online, some starting around $199. Before comparing, ask whether that price includes someone coming to your home, safe sampling, the lab analysis and a written report with locations. Those are what your contractor actually needs. Owners covered by the regulation need more samples per material, and we'll price that up front. Our asbestos testing cost guide goes deeper.

Our own inspectors cover the whole city. We don't have a Toronto street address to list yet, so everything books by phone or through the form.

• Etobicoke: Mimico, Long Branch, the Kingsway, Islington, Rexdale

• Around the city: York Region, Durham, Mississauga and Brampton

Worried about mould in the same basement? We can run mold testing during the same visit. West of the city, our Mississauga air quality testing page covers Peel, and the service areas page lists everywhere else.
